My PI-1500 I mentioned earlier is actually the PI-150 Koala mentioned:







The enclosure is too small to hold your PCB, but maybe there was a bigger box at some point.

Did you hear back from Derek?

Not yet, i wrote short email but sill there is no reply.
Looking at your device i don't see "FAD" command which exists on the other photo i collected from google sites and supposedly is a part of the same device as my pcb.
It could be also the same platform with adaptations made for industrial use... or not, those could also be quite different projects, sharing coincidently only few stages.
Led array on your panel can be driven with same circuit which drives "VU scale" from another model. That tells us nothing particularly.
But you miss "FAD" command and that's most significant difference.
Here it is again:

What is FAD?
Frequency Adjust ?
Full Auto ?
? ? Depth
? ? Discrim
or was it just a "fad"?
